Specification of Letters Patent.

Application filed November 15, 1905". Serial No. 287,462.

To all whom it may concern.-

Be it known that I, HARRY IV. TUTHILL, a citizen of the United States, and a resident of Middletown, in the county .of Orange and State of New York, have invented a new and Improved Window-Screen, of which the fol-- lowing is a full, clear, and exact description.

The, object of the invention is to provide may be extended to fit windows of difierent widths and to provide means for rigidly see curing the screen-sections together.

A further object is to increase the range of adjus'tability'of extensible screens.

The invention consists in the construction and combination of parts to'be more fully described hereinafter and definitely set forth in the claims.

Reference is to be had to the accord anyingl drawings, forming apart of 'his s cc cation, in which similar charactersof re erence indioate corresponding parts in all the figures.

Figure l is an elevation showing the lower portion of a sash, the'window. being provided portion of the screen at one side. Fig.2 is a cross-section throng the lower portion of the screen-frame and taken onthe line 2 2 of Fig. 1. Fig. 3 is a longitudinal-'section'taken' through a-portion of the screen-frame and illustrating its construction in detail. Fig.4 is a cross-section substantially on the line 4'4 of Fig. 2, and Fig. 5 is a cross-section on the line 5 5 of Fig. 1.

Before proceeding to a of the invention it may facilitate the disclosure. to state atthe outset-that the specific p ose of the invention is to provide means or enabling the screen to be extended to its limit without opening a slot connectionwhich constitutes a feature of the invention. With this end in view I provide a sliding late of the screen, but which is extended when the screen is extended, so as toclose the slot, which is opened by the extending of the screen bedetailed description Referring more particularly to the parts, 1 represents a window-casement, the same having a sash 2, adapted to be raised in the usual manner. In applying my screen I rovide vertical cleats 3, which are attache to the sides of the easement, as shown most clearly m. sm-mm nnmnl'ises a frame 4 of substan- .stituteparts of g ,barsfS are provided with longitudinally-disand the bars 9 at suitable" rectangular form and composed of two one upon tially sections 5 and 6, adapted to slide the other in a common manner. At their side edges these sections 5 and 6 are rovided with vertical grooves 7, which are a apted to receive theaforesaid cleats Sin the manner indicated in Fig. 2. The screen-sections 5 "and 6 when put together present a substantially rectangular form, as shown. The section 5- comprises upper-and lower horizontal bars 8, which lie in front of and slide upon corresponding horizontal bars 9, which conposed slots 10,

pointsare provided with bolts 1 1, which pro- "ject through these'slots and carry wing-nuts 12 for the purpose ofclamping-the sections in any should be undergosltion desired. It stoo that the body 13 of the screen is made of suitable wire mesh or suitable material and formed 1nv sections which are attached, re-

spectively,

to the sections 5 and .6 in awellknown mannert', It should beunderstood,

also, that these sections of the screen-body l3 lie close to each'other, so that it is impossible v for insects to passbetween them.- g I form the ars' 8 each with an elongated recess 'o'r groove 14, and these are 7 near the slde of the window-easement, while the SGI'GGIl-SBCi310I16; The

the-slots 1O aforesaid are disposed remotely therefrom and near the extremities of the bars. These grooves or recesses 14 extend, however, throughout substantially the entire length of the bars 8, so-that they comthe slots 10 aforesaid. Withrovided a a long flat municate with in each of these grooves 14 is sliding plate 15, whichconsists o strip, as shown most clearly in Fig. 3. 'Its inner extremity, whichlies near the easement, is formed with a laterally-projecting nib or head 16,'the purpose. of which will appear more full hereinafter. The-outer extremity of-this sllding plate or slide is formed with a longitudinally-disposed slot 17 which coincides with the slots 10, and through each of these slots 17 a corresponding bolt 11 passes. The grooves their point of connection with the slots 10 in such a manner that a projecting shoulder 18 is formed meach slot.

This shoulder is for the purpose of arresting the extending movement of thesliding plate in a manner which will be described more fully hereinafter.

14 are contracted in width near .At the upper edge of the'screen-sections 5 and 6 I provide a channehplate 19, (shown 7 most clearly in Fig. 5,) the same being provided withdownwardly-extending flanges at its edges, which overlap the sidefaces of w 3 the bars of the screensections and hold the mannershown in Fig. I. The sections 5 and same together, as will be readily understood. This channel-plate may be attached, if desired, by any suitable means to the one or the other of the screen-sections. -At .thelower edge of the screen I provide a pair of saddles 'or'clips 2 I, one ofwh ch is shown most'clearlyv in Fig. 4. Each of these clips consists of a "bent plate attached in any suitable manner to one ofthe. screen-sections and having a flange 22 formed at its extremity'retaimng the opposite screen-section, as be readily understood: v

' In using the screen. it should be understood that it will b'e placed in the window inthe go 6 will then. be drawn o'1'1t,' s0 as to fit them te the width otthewindow, When the sections are drawn'a art--iu this manner, the bolts" .11 will run-a n'g in'th'elslots '10.

After the screen is adjusted in this manner to suit the width of the .window the clamping-nuts 12' will bescrewed up, so as to securely hold the parts in an extended position. 11 closing the'screen the bolts 1 1, striking the outer extremities of the slots 17 in the sliding plates,

A screen having sections adapted to slide one upon the otherfone of said sections having slots therein, "bolts carried by the o posite" sections and" received res ectivey through said slots, and sliding p ates'attached toone of said screen-sections and adapted to move therewith to close said slot.

2. A WlIIdOW 'SOI'Q GII comprising in combination, a section having bars with slots there- .1n,' a second section having bars with bolts passing through said slots, sliding plates carried by said first bars and having openings therein receiving said bolts, whereby the movement of said bolts when said screen is extended, will extend said sliding plates.

3. A window-screen comprising in combination, a section having bars with slots theregrooves therein, sliding plates mounted respectively in said grooves, and having slots tension of said screen-sections will extendsaid sliding plates, and means for limiting the extension movement-of said sliding plates.

In testimony whereof I, have signed my name to this specification in the presence of two subscribing w1tnesses.
